construction period - commercial buildings

An estimate of the period of construction for medium size residential buildings can be found  with the following formula:

		PC = 234 * C0.02

		Where:

		PC = period of construction in days
		C = estimated building contract price in $ millions
		.02 = a power factor which can be increased for larger and more complex buildings. 		For example, about 0.50 for a large CBD office tower.

		EXAMPLE

		Estimated building contract price: 	360 000

		PC = 234 * 0.3600.02 
		= 229 days 
		= 7.6 months (round to 8 or 3 quarters)
